2018 Chevrolet Silverado Brakes Problems

Parking brake pad failure has occurred twice. Last month at 31,668 mi, truck was taken in for servicing a warning light due to TPM failure (all replaced), and I asked for parking brake inspection because I was pushing pedal to the floor in order to engage. Mechanic said "Left rear prkg brake shoe has section missing." He had never seen that before and I exclaimed that it happened first in Apr 2021 at 18,770 mi. I am not sure which side it was since it was not written on the service invoice, but I suspect the right side because during a Nov 2021 oil change the invoice included "adjusted rear rh parking brake." OEM replacement pads were installed both times. I have the latest failed pad which shows about 2 in of material missing from the shoe substrate, not the 2021. Kearny Mesa Chevy repaired this in 2021; Walt's Danville Service in 2026. No safety issue, but could have been a problem in event of brake failure an need to stop vehicle by applying parking brake that would not hold. I asked KMChevy if this should be a warranty repair or a recall issue and they refused to consider in 2021. It cannot be coincidence that this happened to Chevy OEM equipment, I suspect to both sides. I paid ~$500 each time and feel that Chevy corporate should compensate me.

ABS warning light came on and brakes starting acting strange. The brake pedal was soft and was hard to depress. I took it to dealer and they checked codes and comfirmed the vehicle has serval codes. They cleared all codes and started the engine. Immediately the ABS warning came on. I am very concenedn about family, I just purchased the truck on Jan 21, 2026. Please help!!

When attempting to stop, the brakes were rock hard and would barley compress. Almost crashed into the car in front of me. Brake booster was replaced a month ago by dealer, but still is losing vacuum. No codes are being thrown, so any reasonable driver would assume everything is fine with the vehicle. It is going to get someone killed.

There is a recall for a brake issue on Chevy Silverados of the same year mine is doing exactly the same as the recall calls for but when I try to get the repair for the recall I’m told my vehicle doesn’t have the recall. The problem almost causes crashes due to the brakes not working when the pedal is pressed.

Vacuum Pump is leaking oil and internal components are rattling indicating imminent failure and that is a safety hazard for the vehicle and passengers. Oil is being slung all over the front of the engine and multiple belts creating additional operating hazards for the vehicle and passengers. There was a recall concerning reprogramming software to reroute air pressure to the brake system and prevent total failures. Also, technical service bulletin addresses related issues to vacuum pump failures and other affected system components. My vehicle is available, no one has looked at it, we are in danger every time we ride in this condition, no indication of failure other than those already stated. My truck is going on 6 years old and 118K miles. Hardly the time for a brake system failure for a normal use vehicle. This is a safety hazard that GM has created by utilizing faulty components and should be treated as such with all vehicles affected recalled for replacement before vehicles and passengers are seriously injured.
